pSeries Systems Handbook
If used, the adapter must be ordered as server feature code and it must be
installed in slot #6 of the server primary I/O drawer. Slot #7 must only be used for
the Internal Attachment Adapter (F/C 3154).
The SP Attachment Adapter uses an SP Switch cable to connect to an unused
switch port on the current SP configuration.
There are some SP-attached server placement limitations. Placement of the
SP-attached server is limited by the length of its following supplied cables:
1. The 10 m (33 ft.) frame-to-frame ground cable and RS/6000 SP System
Attachment adapter cable.
2. The 15 m (49 ft.) RS-232 cables.
Approximately 3 m (10 ft.) of cable is needed for the vertical portion of the cable
runs. Thus, the SP-attached server must be no more than 7 m (23 ft.) from the
SP frame and no more than 12 m (40 ft.) from the control workstation.
3.4.3 SP-attached server configurator rules
Ordering the SP-attached server requires the ordering of both SP features
(cables and installation instructions, as well as tracking for virtual nodes and
frames) and pSeries or RS/6000 features (SP LAN adapter, SP System
Attachement adapter - where attachment to the SP Switch is desired, F/C 3154
for M/T 7026, PSSP code).
Configuring the system order for an SP-attached server to an existing SP
system, consists of an MES order against the SP system to configure the
SP-attached server as part of the SP system.
Note: You must remove the plastic divider between slots 6 and 7 due to the
width of the SP-attachment adapter.
Note: You must order one of the following cables which connect the adapter to
a valid switch port.on the SP Switch:
򐂰 10 m SP Switch/Switch or Switch/Node cable (F/C 9310).
򐂰
20 m SP Switch to Switch cable (F/C 9320).
The cable must be ordered as part of the SP system.
Note: Refer to Chapter 10, “Clustering configurations” on page 285 for more
details about the SP-attached server environment.
